Can anyone tell me what the recommended "typical" cooling rates are after reflow? Are the cooling rates considered as critical to control as the heating rates and why/why not?

All, I would like to find out if it is possible to adjust the cooling rate on a Conceptronic Reflow Oven Model HVN70. We do not use Nitrogen and the Cooloing system is Genesis GCM-1. From profiling it seems to be cooling too quickly. Any replies a

Hi , The 4th stage in reflow soldering, the cool-down, I find is often over looked. A rapid cooling rate should give finer lead and tin structure with more bindings and thereby result in stronger solder joints. Can anybody give me some information

Do a search in the archives on conformal coating and silicone conformal coat. A variety of companies make conformal coatings and the equipment to apply it. Coatings can be applied by dipping the board into the coating, brushing it on, or spraying i

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

Need some input here..... The fear is that the if we use water soluble flux at the repair operation, that the no-clean encapsulation will capture some of the organic material as it cools down and goes to its original state. The organic material wil

Need more information. BUT if your strictly considering just the paste change. I would imagine your changeover would be little to no different than changing to the second board if you were using the same paste. Maybe take extra care cleaning your sq
